Extruding along an area
You can recreate it using a Bezier curve.


Add a Bezier curve, and use the Tilt Tool to adjust the tilt.
Create the profile shape (It needs to be a curve too). The origin point position is important.
Set the profile shape as a Bevel for your curve. It will align based on it's origin point.


Add a Bezier Curve and tilt the control points. Add more control points if needed.



Create the profile shape and set it as a Bevel object. If it's a mesh object, you'll have to convert it first.
